How GPS Really Works (A Plagiarized Parody)

Post by BE_ZERO_BE » Tue May 23, 2023 3:58 pm


The following explanation, in simplified terms, is typical of all GPS navigation systems.

The GPS navigation system knows where it is at all times.
It knows this because it knows where it isn’t.
By subtracting where it isn’t from where it is or, where is from where it isn’t (whichever is greater), it obtains a difference of deviation.

The GPS navigation system uses deviation to generate corrective commands to drive the system from a position where it is to a position where it isn’t, arriving at the position where it isn’t, it is now.
Consequently, the position where it is, is now the position where it wasn’t and it follows that the position where it wasn’t is the position where it isn’t.

In the event the position where it is now isn’t the position where it wasn’t, the GPS navigation system acquires a variation (variations are caused by celestial factors and discussion of these factors is not within the scope of this discussion).
The variation is the difference between where the GPS is and where the GPS wasn’t.
If the variation is considered to be a significant factor, it too may be corrected by the GPS navigation system, however, the GPS navigation system must know which where it wasn’t to determine which where it isn’t.

The GPS Navigation System Thought Process :

Because a variation has modified some of the data that the GPS navigation has obtained, it is not sure where it is.
However, it is sure where it isn’t (within reason), and it knows where it was but may not know where it wasn’t.
It now subtracts where it should be from where it might not have been and differentiates this with the algebraic sum of the deviation and the variation of the last known position where it wasn’t and the position where it isn’t to produce an error to which it compensates for all external factors and thus provides accurate navigation information to guide you along your way.

Simple.

I drive a Model T ... Microseconds don't matter :D

For every Absolute Model T Fact there are at least three exceptions.

i guess that's why it does not always take you to the right destination. Sometimes takes you by a shorter route but on a dirt road or some other slower route even though it might be a bit closer.

Open the pod door, Hal.
I'm sorry Dave, I can't do that.

Exactly! It's not science fiction anymore. :shock:
Where did I put my map and compass? No thank you Alexa, I'll find it myself. :)

I know from my experience that GPS cannot be relied on.I had a cause when it took me to another place. And one day it chose a route where I got into a big traffic jam.

From my earliest age, I was pushed to think for myself and find better
ways to get things done. Why is it in the past few years that the world
has decided to quit thinking for themselves ?
More people are doing it today than ever before !

If you think for yourself, then when you're lost, you can ONLY blame yourself. :o
